摘要
为了提高雷达的作战能力 ,需提高雷达的抗干扰能力 ,其中雷达频率的捷变是提高雷达抗干扰的一种途径 .雷达频率的变化应具有针对性 :利用干扰分析系统将外界干扰信号检测出来 ,判明干扰信号概率 ,使雷达发射机利用干扰频率最弱点 ,避开强干扰频率点 .该方法使雷达能够快速准确搜索到目标 。
In order to increase the campaign capability, the anti disturbance capability of radar needs to be improved. Radar rapid convergence technology is one method of increasing its anti disturbance capability. But the frequency change of the radar should be pertinent. Takes advantages of the interference analysis system to check out the interference signal and judge its probability. By making use of the weakest interfering frequency the radio emission can avoid the strongest interfering frequency. With the above mentioned method the radar can search the target rapidly and accurately, predict various threats and provide the optimum command selection.
